I have owned three universal players. I still have two. The Pioneer DV-45A, the Pioneer DV-563A, and my current A-team unit, the Denon 3910. I bought all three used on Ebay. The 45A was under $200. The 563 was under $100, and the 3910 was about $800 shipped. All units performed excellently, and played all discs I asked them to. The sound and picture quality of all three was excellent, with the 3910 stepping it up a notch on most levels, and most noticeably on sound quality in multi channel formats. All three were used with analog interconnects and component video. For build quality the Pioneer's were about up to their price range. The 3910 weighed noticeably more, and was much more solid in all facets. I would reccomend all three units and feel like they cover all the bases in your price range.
I just checked on ebay. The 563As are going for under $30! shipped. No remote, but hey, this is a universal player!
